Question

a body of mass 5 kg is thrown vertically upward with an initial velocity of 50m/swhat will be its potential energy at the end of 5 seconds where g=9.8m/s​

Answer 1

Answer:

Given,

m = 5kg,

u= 50m,

t = 5s,

g = 10m

Height covered by the body in 5 s is h = ut + 1/2at*t

formulation,

= 50x5 - 1/2 x10x 5 x 5

= 250 - 125= 125 m

Therefore, PE of the body after 5 s

= mgh = 5 X 10 x 125 = 6250J

Answer 2

Explanation:

6250 joules
